What is LED lighting power

What is LED lighting power factor? Led lighting power factor is an important parameter to  LED Bulb  understand what is the power factor is conducive to further our understanding of LED lamps.

1, the power factor

Characterization of the lamp output power factor active power capability. Power transmission rate is a measure of the energy in the DC circuit it is the voltage V and current A and the product. In the exchange system will have more complex: that is part of the AC current in the load cycle is not in power transmission, which is called reactance currents or harmonic current, which makes the apparent power (voltage multiplied by current Volt Amps) greater than the actual power. LED Module Apparent power and actual power leads to unequal power factor, power factor equal to the actual power and apparent power ratio. So AC power is equal to the actual system apparent power multiplied by the power factor. Namely: Power factor = real power / apparent power. Only electric heaters and light bulbs linear load power factor is 1,
